The purposes of this study were to investigate the effects of university foodservice quality attributes on Chinese students' satisfaction, as well as the mediating effects of perceived value on the relationship between foodservice quality attributes and satisfaction. A total of 250 university students in Daejeon were surveyed, and 216 responses were returned. Excluding responses with significant missing data, 196 responses were used for data analysis. The reasons for using university foodservice were 'meal plan' (37.8%) and 'time saving' (22.4%), whereas the reasons for not using university foodservice were 'untasty food' (33.2%) and 'limited menu selection' (27.6%). Results confirm that enhanced performance of food quality, service quality, sanitation, and convenience had favorable effects on perceived value and satisfaction. Further, perceived value had a significant positive influence on satisfaction. In analyzing the mediating role, the effect of foodservice quality attributes on satisfaction was partially mediated by perceived value.

Limestone areas are sedimentary rock outcrops consisting of calcium carbonate created several hundreds of millions of years ago by calcium-secreting marine organisms and subsequently lifted above sea level by tectonic movement. Limestone areas support very high levels of endemic species of plants and are recognized as biodiversity areas with much biological information. The purpose of this study is to devise a strategy for the comprehensive conservation of the vegetation of limestone areas through analyses of the floristics and plant species compositions in ten limestone areas on the Korean Peninsula. The results of 153 field surveys from April of 2010 to October of 2016 identified 1,202 taxa in total, representing 1,096 species, 18 subspecies, 84 varieties, 2 forms, and 2 hybrids in 530 genera and 133 families. Among them, 55 taxa were endemic plants to Korea, and 38 taxa were red data plants. The floristic target plants amounted to 102 taxa, specifically 27 taxa of grade V and 75 taxa of grade IV. In all, 121 alien plants were recorded in the investigated area. Calciphilous plants amounted to 102 taxa, specifically 14 taxa of calciphilous indicator plants, 30 taxa of superlative most calciphilous plants, and 58 taxa of comparative more calciphilous plants. A cluster analysis showed a high degree of similarity between sites that are geographically adjacent with similar habitat environments. Limestone areas also supported groups distinct from those in non-limestone areas, demonstrating the specificity of limestone flora. Plant geography approaches therefore appear to be crucial to gain a better understanding of the level of biodiversity in limestone areas, not only at the interspecific but also at the intraspecific level. These results highlight the importance of protecting limestone habitats to preserve not only their interspecific but also the intraspecific diversity, which is highly threatened.

The purpose of this research examines the factors that influence happiness among Korean adolescents by focusing on psychological resource (as measured by self-efficacy), relational resource (as measured by social support) and financial resource (as measured by family's monthly income). In addition, the influence of academic achievement on happiness is examined. To examine the influence of socio-economic status and family's monthly income, adolescents living in three different districts in Seoul (from working to middle to upper class districts) were randomly selected and interviewed in their home. A total of 190 elementary school, middle school, high school and university students (male=83, female=107) completed the resiliency of efficacy scale developed by Bandura (1995) and emotional support and happiness scale developed by the present researchers, in addition to background information. The results of the path analysis are as follows. First, the most important predictor of happiness among Korean adolescents is relational resources. In other words, emotional support received from significant others was most predictive of happiness; more than 60 times the effect of family's monthly income, three times the effect of academic achievement, and two times the effect of resiliency of efficacy. The second most important factor that predicted the happiness of Korean adolescents was psychological resource (i.e., resiliency of efficacy), which had 30 times the effect of family's monthly income. In addition resiliency of efficacy played a mediating role between emotional support on one hand and happiness on the other. Third, those respondents who had higher academic achievement reported higher levels of happiness, which had 20 times the effect of family's monthly income. Fourth, family monthly income did not predict happiness among Korean adolescents. Fifth, socio-economic status and school level did not have direct influence on happiness but had mediating influence through their influence on emotional support. In other words, those respondents with higher socio-economic status and elementary school students were more likely to receive social support from significant others, which in turn increased their happiness. These results indicate that the most important predictor of happiness among Korean adolescents is emotional support, followed by resiliency of effic acy and academic achievement, indicating that those adolescents from wealthy families are not necessarily happier.

This study examines the formation and change of relational trust among Korean adolescents using indigenous psychological perspective. Among adolescents, we examine the basis of trust of their parents, friends and teacher and also their trust in people and institutions. A total of 968 adolescents (227 elementary, 284 middle school, 213 high school, and 244 university students) completed a questionnaire that contains the Relational Trust Scale developed by Kim and Park (2004a), Generalized Trust Scale developed by Yamagishi (1998) and a scale measuring trust of people and institutions (Kim, Helgesen & Ahn, 2002). The results are as follows. First, adolescents trust their parents due to their sacrifice, followed by their counsel and advice, dependability, consanguinity and respects. They trust their teachers due to their counsel and advice, followed by respect, sacrifice, and mutual trust. They trust their friends due to their advice, followed by empathy, mutual trust, dependability, friendship and sacrifice. Second, trust of their parents are highest among the elementary school students and lowest for the middle school students and lower for older age groups. The trust in teachers are highest among the elementary school students and lowest among the middle school and university students. In contrast, trust in friends increase from elementary school students to older age groups. Third, among trust in people and institutions, they are highest for parents and family and lowest for politicians and political parties. Except for trust in friends, trust of significant others and institutions (family, teachers, neighbors, company executives and politicians) is highest among the youngest age group and it decreases with older age group. Fourth, Yamagishi's generalized trust was highest among the older age groups (high school and university students). The patterns of results for relational trust and generalized trust is different and it points to the importance of understanding trust from the indigenous psychological perspective.
